Facecrack(book) took over my life for about a month or so. I found all kinds of people on there that I haven't seen or heard about in years. When I joined, Facebook was still new. Now it is different, too many applications to add and stuff. I am done with it. It has served it's purpose and reconnected me with old friends.
It is addictive though, until you find everyone, set it all up and stuff.
I find myself here more often now, I like it better here.
